Access arrangements

Every five years Western Power prepares an access arrangement review so we can revise the services we offer and update the prices we charge.

The Economic Regulation Authority (ERA) negotiates on behalf of the Western Australian community with Western Power before approving an access arrangement. Generally, it’s electricity retailers and generators such as Synergy who apply to gain access to the network, so they can transport electricity to customers.

To prepare our submission, we meet with customers and community representatives to understand what energy services and solutions they need and value, now and into the future. The results help to shape the current and future focus of Western Power so we can deliver on their energy needs.

On Tuesday, 1 February 2022 the proposal for our fifth access arrangement period (AA5) was submitted to the ERA and covers the five-year period from 1 July 2022 to 30 June 2027.

The ERA will now publish our AA5 proposal for public comment. Towards the end of 2022, the ERA will publish their draft decision on our proposal and provide us with the opportunity to make amendments to address any issues raised during the public consultation period. The ERA’s final decision is expected in early 2023.

Information on our access arrangements can be found on the  ERA's website.
